Features PL1877A Microprocessor Radio Telephone Interconnect
12/10 124
Parameter Function
1085 The number of digits accepted from a mobile user for selective signaling. The valid
range depends on the type of signaling selected:
DTMF, 2805, 1500 = 0–6
2-Tone = 0–3
Plectron = 0–4
Motorola/EIA = 0–6
N OTE : Parameters 1083, 1084, and 1085 apply only if multi-mode selective signaling has not been
selected. If one of these parameters has been set to 0, the same paging sequence is generated every time.
For example, if parameter 1083 = 0, the PL1877A automatically pages the preprogrammed capcode every
time the landline user dials into the patch.
Multi-Mode
Parameter Function
1179 to 2878
The multi-mode paging parameters create a table of the user IDs associated with multi-
mode paging. It consists of up to 100 entries in a 17-byte pattern. The pattern for each
entry is described below:
1. The first byte is to be entered using the format wxyzaaa. aaaa defines the paging type
of the user ID. Paging types, as defined in parameter 1081, are:
0 = DTMF
1 = 2-Tone
2 = Plectron
3 = 2805
4 = 1500
5 = Motorola/EIA 5 Tone
8 = TPL
9 = DPL
If this byte is set to $F (the multi-mode selection), this entry is disabled.
If z is set to 1, direct channel access is granted following paging even if it has been
previously disabled in parameters 58, 42 and/or 59.
If the capcode for this user ID specifies a group call, and parameters 1009, 1010, or 1011
are set to disable group call generation, bit y must be set. If the selected paging type for
this user is Motorola 5/6 tone, six digits have been entered, and parameter 1012 is set to
disable dual addressing, bit y must be set.
If parameter 1004 is set to deactivate the PL strip output during selective signaling tones,
but it is necessary to activate this output when paging this particular user, bit x must be
set.
If parameter 61 is set to deactivate the PL strip output during direct access time, but it is
necessary to activate the PL strip output during direct access after paging this particular
user, bit w must be set.
2. The second byte links the user ID to another user ID. If the PL1877A receives no
answer after paging this user the required number of times, it pages the user ID#
specified by this byte. The valid range for this entry is 0-99. This entry must have the
ten’s digit of the user ID in the four most significant bits and the one’s digit in the four
least significant bits.
For example, for user ID 36, enter $36 (hexadecimal 36).
This feature allows you to create a “chain” of user IDs. If the PL1877A receives no
answer to a page, it advances to the next user ID in the chain. This process continues
until the PL1877A reaches a user ID with no linked ID or until the PL1877A pages a
user ID that requires direct access following paging (bit z = 1).
